PROTECTING-SEAL.

Specification of Letters Patent. Patented NOV, 24,1914,

Application filed April 27, 1914. Serial No. 834,562.

Be it known that I, CHARLES A. GILLING- HAM, a citizen of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Protecting- I Seals, of which the following is a full, clear,

and exact description.

This invention relates to improvements in protecting seals for dry batteries. Such seals are a protection for both the seller and user, and are constructed in such manner that the terminals are exposed to permit voltmeter or ammeter leads to contact therewith to determine the condition of the bat tery. It is necessary, nevertheless, to break the seal before the terminals or binding posts of the battery may be connected up in the manner in which they are intended to be used. By this arrangement, the :purchaser may try the voltage of the battery to determine whether it is in good condition,

" before accepting, without tearing the-seal.

If the battery is old and has deteriorated through shelf life or other-causes,-it may be re ected by the customers without destroying the seal. However, upon breaking the seal, the purchaser forfeits the right to ask for replacement if unsatisfactory, which protects the dealer from fraudulent 01311115 regarding the condition of the article when it was sold. The purchaser, by obtaining sealed batteries is also insured against obtaining used or partially used cells, so that I a mutual benefit is derived.

My invention relates to an improved seal for accomplishing the results set forth.

- My protective seal also serves to alarge extent to prevent accidental short circuit ng of the terminals of the battery before it is placed in use.

\Vhile the invention is illustrated'm connection with a midget battery for earphone purposes and especially adapted therefor,it will be understood that it is applicable to other batteries having pro ecting terminals In the drawings: Figure l is a perspective view of an earphone dry battery without a seal. Fig. 2 is a top view of the battery w th the seal applied thereto. Fig. 3 is a side view of the battery and seal. Fi 4 is a partial cross section taken on the hie A-A of Fig. 3.

The battery casingl containing. a numberof zinc-carbon dry cells h asterminals such as the metal rods 2, 3 projecting from the top. These terminalsare -adaptedto be readily fitted into a socket connected to the earphone. However, any. type of binding posts or terminals might be used in connection with the seal as hereinafter described.

The protectingseal consists of a piece of cardboard 4 scored and bent intoan angular or trough form and open at both ends. The apex of the trough is adapted to cover the ends of the terminals 2, 3 andthe sides are preferably of sufficient length to fit just.

flush with the sides of the battery casing when the apex rests on the terminals. The

hood or trough is then sealed tothe casing by means of a thin strip of adhesive paper 5 which is affixed at each end to the sides of To make the'terminals more-readily acces-- .said casing and also to the trough or hood.

sible, each of the four corners of the card board cap 4 is cut. oil as shownin the drawings.

Referring. to Fig. 3 it will be evident that i the terminals 2, 3 are exposed so'that the- 'leads ofan electric meter may be readily dition of sale will be set forth in a printed notice upon the seal.

Having described my invention, what I claim is:

1. An electric battery, a projecting terminal, a trough shaped insulating member extending from said terminal, and resting on the top of the said battery and means to seal said member in position over the terminal whereby the battery cannot be used without breaking said sealing means.

2. An electric battery, rigid-pro ecting terminals, trough shaped covering inverted over said terminals and having its sides resting on the top of the battery, and means to seal the member in place, whereby the battery can be tested but not put to its intended use without breaking the seal.

3. An electric battery, rigid terminals pro jecting from the top. thereof, a trough shaped insulating covering inverted over theterminals with the bottom in enga e men-t therewith anathe sids resfing on the top, of the battery, and a strip passmg OVQI. said. member and secured-to each and tn-the sides of the battery.
